A Platform-Based Software Design Methodology for Embedded Control Systems: An Agile Toolkit

A discrete control system, with stringent hardware constraints, is effectively an embedded real-time system and hence requires a rigorous methodology to develop the software involved. The development methodology proposed in this paper adapts agile principles and patterns to support the building of embedded control systems, focusing on the issues relating to a system's constraints and safety. Strong unit testing, to ensure correctness, including the satisfaction of timing constraints, is the foundation of the proposed methodology. A platform-based design approach is used to balance costs and time-to-market in relation to performance and functionality constraints. It is concluded that the proposed methodology significantly reduces design time and costs, as well as leading to better software modularity and reliability

EFFECT OF PLANT POPULATION IN GREAT NORTHERN AND PINTO BEAN PRODUCTION IN WESTERN NEBRASKA

INTRODUCTION In this project we explored the effect of plant population and row spacing on the yield and quality of great northern and pinto beans grown in Nebraska. This project builds on the findings from a preliminary non-replicated great northern variety trial conducted at Morrill, NE in 2014. That trial included four great northern cultivars with different plant architecture. In general, yields were reduced 18.8% (795 kg ha-1) when plant population increased from 251,152 to 300,715 plants ha-1. Yield reduction was greatest in ‘6107’ (24.7%) followed by ‘Marquis’ (20.1%), ‘Beryl-R’ (15.5%) and ‘Coyne’ (14.0%). In the current project we used replicated trials to evaluate the impact of plant population on two great northern and two pinto bean cultivars. Within each market class, one cultivar had a prostrate (III) and the other had an upright (II) growth habit. Our goal was to identify the optimal plant population and row spacing for each cultivar. MATERIALS AND METHODS This study was conducted during 2015 at the PREC-Scottsbluff, NE. Two great northern, ‘Marquis’ (III) and ‘Draco’ (II), and two pinto cultivars, Montrose (III) and Sinaloa (II) were planted in separate experiments at two row spacing (15 and 30 inches) and four plant populations. Target populations for the 30-inch row spacing were 45,000, 80,000, 100,000, and 120,000 plants/acre. Target populations for the 15-inch row spacing were 80,000, 100,000, 120,000, and 150,000 plants/acre. Four and seven rows were planted for the 30- and 15-inch row spacing experiments, respectively

THE STATE MANAGEMENT CAPACITY INDEX IN MEXICO: A TOOL FOR MEASURING PUBLIC POLICIES IN LOCAL GOVERNMENTS

The main purpose of this paper is to present the results of the construction of a methodological instrument called the Subnational Local Governance Index (ISGL). This Index was built to contribute to the assessments of institutional capacities of local governments, in order to resolve public problems in Mexico. The construction of the Index was founded on four main features: 1) The lack of public policy in education, health, public services and housing quality, measured by the level of social backwardness, 2) the structure of government and administration, measured by the institutional capacities, 3) the quality of local government, measured by the level of credibility of the citizens through subnational governance and 4) the local financial capacity, measured by the ability to generate income and to manage the public debt. Basically, the following questions have been used to build the Index: What is the level of social backwardness at the local level? What kind of institutional structure exists at the local level? What is the profile of the public policy managers at the local level? What is the capacity to generate income? What is the level of citizens’ confidence in local governance

Caracterização petrológica e geocronológica da Suíte Alcalina Monte Santo, na região de Paraíso do Tocantins

Dissertação (mestrado)—Universidade de Brasília, Instituto de Arquitetura e Urbanismo, Departamento de Urbanismo, 2018.A Suíte Monte Santo é consituída de dois maciços foliados, variavelmente deformados e metamorfizados (Maciço Estrela e Monte Santo). As intrusões são dominadas por nefelina sienito e feldspato alcalino sienito, mas nefelina monzosienito e nefelina monzodiorito subordinados também estão presentes. Nesse estudo, a química, mineralogia e idade da Suíte Monte Santo foram investigadas. Os cristais de piroxênio variam em composição entre onfacita e aegirina-augita e tem características mistas entre tendências ígneas e metamórficas. Os cristais de biotita variam de flogopita para siderofilita e annita, e apresentam tendências primárias, reequilibradas e neoformadas. Os cristais de anfibólio variam de hastingsita para taramita, e apresentam química muito homogênea. Nefelina apresenta cristais de alta temperatura preservados na paragênese, mas também muitos cristais de baixa temperatura. A maioria das rochas da Suíte Monte Santo não plota nos pontos mínimos no Sistema de Resíduo Petrogenético, além disso, os padrões de elementos terras raras e outros elementos traço demonstram tendências paralelizadas com variações significativas em concentração, sugerindo que a maioria dessas rochas representem cumulados. Os padrões Zr/Hf são similares para todas rochas do maciço, demonstrando que elas evoluíram da mesma fonte. Cristalização fracionada foi o processo principal de diferenciação magmática. A cristalização da Suíte Monte Santo é datada em 545 Ma, onde essas rochas foram geradas em uma fase extensional ou transtensiva na evolução do orógeno e foram subsequentemente deformadas e metamorfizadas em fases compressivas seguintes. Idades TDM, anomalias positivas de Nb e Ta e as formas irregulares encontradas em cristais de zircão Mesoproterozóicos datados nessa suíte sugerem que a Suíte Monte Santo evoluiu de uma fonte mantélica Mesoproterozóica, herdando alguns de seus cristais de zircões.The Monte Santo Suite consists of two foliated and variably deformed and metamorphosed massifs (Estrela and Monte Santo). The intrusions are predominantly nepheline syenite and alkali feldspar syenite, but minor nepheline monzosyenite and nepheline monzodiorite are found in the Estrela Massif. In this study, the chemistry, mineralogy and age of the Monte Santo Suite were investigated. Pyroxene crystals vary in composition from omphacite to aegirine-augite to aegirine and have mixed characteristics between igneous and metamorphic trends. Biotite crystals vary from phlogopite to siderophyllite to annite and presents primary, reequilibrated and neoformed trends. Amphibole crystals vary from hastingsite to taramite and have an homogeneous compositions. Nepheline presents high-temperature crystals preserved within the paragenesis but also many low-temperature crystals. The rocks of the Monte Santo Suite mostly do not plot near the minimum in Petrogeny’s Residua System. Additionally, REE and trace element patterns depict parallel trends with significant variations in bulk content, suggesting that most of the rocks represent cumulates. Zr/Hf ratios are similar for all the rocks of the massif, showing that they evolved from the same source. Fractional crystallization was the main process that determined the lineage between different rock types. The Monte Santo Suite crystallization age is dated to 545 Ma, when these rocks were generated in an extensional or transtensional phase of orogen evolution and were subsequently deformed and metamorphosed in a compressive phase. TDM ages, positive Nb and Ta anomalies and many irregularly shaped Mesoproterozoic zircon crystals suggest that the Monte Santo Suite evolved from a Mesoproterozoic mantle source, inheriting some of its zircons

The VMC Survey. XXII. Hierarchical Star Formation in the 30 Doradus-N158-N159-N160 Star-forming Complex

We study the hierarchical stellar structures in a ∼1.5 deg2 area covering the 30 Doradus-N158-N159-N160 star-forming complex with the VISTA Survey of Magellanic Clouds. Based on the young upper main-sequence stars, we find that the surface densities cover a wide range of values, from log(pc2) ≲ -2.0 to log(pc2) ≳ 0.0. Their distributions are highly non-uniform, showing groups that frequently have subgroups inside. The sizes of the stellar groups do not exhibit characteristic values, and range continuously from several parsecs to more than 100 pc; the cumulative size distribution can be well described by a single power law, with the power-law index indicating a projected fractal dimension D2 = 1.6 ± 0.3. We suggest that the phenomena revealed here support a scenario of hierarchical star formation. Comparisons with other star-forming regions and galaxies are also discussed.Fil: Sun, Ning-Chen.

An algebraic approach for action based default reasoning

Often, we assume that an action is permitted simply because it is not explicitly forbidden; or, similarly, that an action is forbidden simply because it is not explicitly permitted. This kind of assumptions appear, e.g., in autonomous computing systems where decisions must be taken in the presence of an incomplete set of norms regulating a particular scenario. Combining default and deontic reasoning over actions allows us to formally reason about such assumptions. With this in mind, we propose a logical formalism for default reasoning over a deontic action logic. The novelty of our approach is twofold. First, our formalism for default reasoning deals with actions and action operators, and it is based on the deontic action logic originally proposed by Segerberg in [27]. Second, inspired by Segerberg?s approach, we use tools coming from the theory of Boolean Algebra. These tools allow us to extend Segerberg?s algebraic completeness result to the setting of Default Logics.Fil: Castro, Pablo Francisco.
